Stems

Leaves

Leaves are long-oval, long-stalked with a few rounded teeth. Upper leaves are alternate, while the lower leaves are opposite. They are water-repellent, so after it rains, they are covered with raindrops or tiny "jewels".

Flowers and Fruit

Flowers are trumpet-shaped, blooming from early summer to fall. Flowers have three petals, one curving to form a long slipper-shaped spur. Spotted jewelweed plants have yellow-orange petals with red, yellow or white spots.

Distinguishing Features

Medicinal uses

Jewelweed has been used as an "anti-itch" remedy in the treatment of dermatitis resulting from poison-ivy.
However, several studies have found that jewelweed extract is not effective in the treatment of dermatitis resulting from poison ivy or poison oak.
